FAULT SOURCE REMEDY
Steam and moisture. A false alarm may be triggered if the
smoke alarm is positioned to close to a bathroom, laundry
room or other areas where ambient humidity is high.
Position the smoke alarm at least 2 metres away from the
bathroom, laundry room or other locations where ambient
humidity may be high.
Dust and dirt. The smoke alarm will attract a certain amount
of dust and pollen particles as the air passes freely through the
detection chamber. This may lead to false alarms. The smoke
alarm may also become more sensitive on account of this,
which may result in unwanted alarms.
Vacuum the smoke alarm regularly, use a plastic nozzle so as
not to damage the electronics. Avoid installing smoke alarms
in locations where there is a lot of dust and dirt. Ideally, place
a “hood” over the smoke alarm or remove it entirely while you
are carrying out renovations at home.
Draughts, dust and air flows. False alarms may be caused if the
smoke alarm is placed too close to doors, windows, ventilation
systems, fans, air ducts, heat pumps and suchlike. This may
cause dust particles to fly up and into the detection chamber.
Do not install smoke alarms in draughty locations or close to
windows or doors, ventilation, fans, air ducts, heat pumps
and suchlike. Find a better location for your smoke alarm,
further away from draughts and air flows.
Temperature variations may cause condensation in the
detection chamber – if the smoke alarm is placed in a room
where windows are opened for ventilation in winter, for
example, or close to exits, balcony doors or other locations
where conditions switch between hot and cold.
Avoid installing smoke alarms in rooms where the
temperature changes rapidly or close to windows or doors
that are opened and closed frequently. Move the smoke
alarm to a location where the temperature is more consistent
and stable.
Adverse location. Positioning the smoke alarm incorrectly in
an unstable indoor environment may lead to false alarms due to
draughts, close proximity to electrical devices (EMC) and lighting.
Position smoke alarms at least 5 metres away from
fireplaces, stoves or other heaters. 2 metres away from
ventilation ducts, heat pumps and air conditioning.
1 metre away from lamps and fluorescent tubes.
